PDF Remediation, Without the Per-Page Invoice

Human remediation services charge $3–10 per page and take days. The machine-checkable layer — most files' actual problem — takes minutes here.

Search for PDF remediation and you'll find quote forms: real humans retagging documents at $3–10 per page with multi-day turnaround. That's the right answer for gnarly, high-stakes documents — and massive overkill for the everyday case: a born-digital report or policy PDF that simply was never tagged. Ceereo is the self-serve lane: upload the PDF, get the free audit, and download a remediated version in minutes — tags, reading structure, artifacts, language, title, alt text — with machine verification and a pixel-diff proving the visual file is untouched.

How it works

From upload to accessible PDF in four steps

The fastest way from an inaccessible PDF to a tagged, verified one — no tag panel, no service queue, no visual changes.

  1. Step 1

    Upload your PDF

    Drop in the PDF you need to make accessible. Your file is processed only to audit and remediate it, and is never used to train models.

  2. Step 2

    The document is audited

    Every PDF/UA and WCAG machine check runs: tags, reading order, language, title, alt text, font embedding and text integrity.

  3. Step 3

    The structure is written in

    Headings, paragraphs, lists, tables and figures are tagged in reading order, with headers and footers marked as artifacts to be skipped.

  4. Step 4

    Download the accessible PDF

    Get your own file back with a full tag structure, re-audited and pixel-compared so you can prove nothing visible changed.

In short

PDF remediation means adding the accessibility layer — tags, reading order, alt text, metadata — to an existing PDF. Human services charge $3–10/page with days of turnaround; Ceereo remediates born-digital PDFs in minutes at a flat per-document price, machine-verified and visually identical.

What does PDF remediation cost?

Human remediation services typically charge $3–10 per page (complex documents higher), so a 50-page report runs $150–500. Automated remediation of born-digital PDFs costs a flat per-document price — a fraction of one page's service rate — and finishes in minutes. Scanned documents and complex forms still justify human services.

The self-serve lane

Most PDFs don't need a human — they need tags

The dirty secret of remediation queues: a large share of submitted files are clean, born-digital documents whose only crime is being untagged. Automating exactly that class — and honestly refusing scans and forms — is why this can cost dollars instead of hundreds.

Why not do it by hand?

Ceereo vs. doing it manually

Remediating a PDF by hand in Acrobat's tag panel takes days and rarely verifies clean the first time. Here's the difference.

Output quality

What the remediated PDF looks like

Every run produces a tagged, machine-verified PDF that is pixel-identical to your original. Here's what you get.

  • Full tag structure + artifacts + metadata in the original file
  • Machine verification (PDF/UA checks) before download
  • Pixel-identical output, proven per page
  • Before/after report for your records

Frequently asked questions

When should I still hire a human service?+

Scanned documents, complex interactive forms, and documents where nuanced reading-order judgment is legally critical. For born-digital text documents, automation covers the machine-checkable layer those services bill hours for.

How is quality verified?+

The output is re-audited against the same PDF/UA machine checks and pixel-compared with the original — both results are shown before you download.

Do you keep my documents?+

Files are processed to produce your output and report; they are not used for anything else.
